A double-pass forward pumping(DPFP) broadband Er3+/Yb3+ co-doped superfluorescent fiber source at(1.55μm) is demonstrated and experimentally investigated.The output power,mean wavelength and bandwidth of the source are studied on three different length fibers when pumped near 976nm and operated in their optimal pump power.The experimental results show that the fiber source of a 60cm Er3+/Yb3+ co-doped fiber behaves better than the others.A maximum output power of 9.18mW and a bandwidth of only 34nm are achieved simultaneously with mean wavelength stability of 7.16×10-6m/mW.If decreasing the output power to about 3.78mW,a maximum bandwidth of more than 80nm can be acquired.
